An introduction to the EarthRes program

The High-Resolution Earth System Modeling, Analysis and Prediction for a Society Resilient to Hydrometeorological Hazards (EarthRes) is a program of the International Decade of Sciences for Sustainable Development (IDSSD), endorsed by UNESCO in 2025. EarthRes aims to build global societal resilience to hydrometeorological hazards through five pillars: (1) establishing cooperative observation networks; (2) advancing process-based understanding of Earth system dynamics; (3) enhancing prediction and early warning capabilities; (4) fostering indigenous and local knowledge and data sharing; and (5) strengthening capacity building among international partners.This presentation will introduce the program's recent progress, including collaborative observations for understanding Earth system dynamics, the integration of a regional climate model with a coupled land surface-hydrology-ecology model that accounts for human activities (e.g., reservoir regulation, irrigation, urbanization), and the development of a forecasting framework. This framework connects the regional model with an AI model to predict droughts, floods, and compound events at synoptic to sub-seasonal scales.Other activities under EarthRes will also be introduced, and future plans will be discussed. Through international collaboration and targeted capacity-building, EarthRes seeks to enhance sub-seasonal prediction and early warning capabilities, with particular benefits for vulnerable regions.
